| dc.description.abstract | Liquefaction-induced damages has proved to be severe, widespread and complex in recent earthquakes. Dynamic effective stress analysis is a procedure for evaluating the seismic response of geotechnical systems experiencing liquefaction due to earthquakes. The robustness of an effective stress analysis significantly depends on the suitability of the constitutive model used. Rigorous verification and validation of constitutive models are crucial to assess the capabilities and limitations of a model for further analyses. Comprehensive documentation of such studies provides the engineers and researchers with insight into selecting the best model for any existing circumstances. The stress density model is a constitutive model for effective stress analyses involving liquefaction, which has been recently implemented in OpenSees and FLAC. This study presents cross-platform comparisons of the stress density model implementation in both platforms through 1D free-field site response modelling of previously conducted centrifuge tests. The performance of the model when capturing the acceleration response and pore water pressure accumulation/dissipation at critical locations is evaluated. | en |
